phrase invented by a mouldy man called max from T-side and bout other 20 places, hardcore buzzer who headkicks anyone that gives him cheek, also denies his doing well in tests, he really is a true GAS FEEN

when someone does something vaguely funny, a jiver will then shout 'gas feen gas feen' or 'gas boii gas boii', it may also be sarcasm, it is now catching on as a common phrase in galway cos maxim influences everyone cos he is well hard
